Specification of Letters Patent.

Patented' Feb. 4, 1919.

Application led. August 20, 1917. Serial No. 1817,800.

To all whom it may concern:

Be it known that I, WILLIAM J. BnRenNs, a citizen of the United States of America, and a resident of Muskegon, in the county of MuskegomState of Michi an, have invented certain new \a`nd useful Improvements in Mixing-Valves, of which the following is a specification.

This invention relates to that class of multiple valves adapted for convenient manipulation by 'a single operating means to deliver water of any required temperature for lavatory and like uses, and the present improvement has for its object To provide a compact, durable and eilicient structural formation and association of parts, whereby the user is enabled to obtain allow of water of the desired temperature alc 1, with the lateral in a ready and certain manner and with which the inflowing streams of hot and cold water are effectively mixed in a thorough manner, as will hereinafter more fully appear.

In the accompanying drawings:

Figure 1, is `a plan view of the present valve.

Fig. 2, is an elevation of the same.

Fig. 3, is a horizontal section.

Fig. 4, is a vertical section.

Fig. 5, is a detail section of a modification.

Like reference numerals indicate like parts in the several views.

Referring to the drawings, 1 designates the central and Vmain casing of the valve, preferably of a circular shape, and having an approximately flat and integrally formed bottom web or wall 2 and a removable top wall or cap 3 provided with a packing gland 4 which receives the centrally arranged operating spindle or stem of the valve mechanism.

5 and 6 designate counterpart radially disposed T shape valve casings arranged at opposite sides of the main casing 1,' and preferably in axial alinement with each other as shown. Said valvel casings 5, 6 are preferably formed integral with the main casing branches 7 8 of the respective valve casings 5, 6 adapted for individual connection to the respective hot and cold water trunks 9 and 10 by union couplings l1 and 12. Said trunks 11, 12 are preferably of the ordinary offset form shown.

13 and 14. designate closure caps fitting the outer ends of the respective valve casi lings 5, 6, and permitting ready access to the valve mechanisms contained in said casings for repair and replacement.

15 and 16 designate removable screw bushingsl tting annular ledges' or partitions inside the casings 5, 6, and'constituting the valve seats thereof.

17 and 18 designate the movable valve members of the structure, of any usual detail construction and having guidel stems 19, 20 moving in the central bores of the bushings 15, 16 with into the chamber of the main casin .1 for operation by the mechanism hereina ter described. 21,21 designate partitions arranged in transverse relation to the axis of the valve members 17, 18, and formed with guide orices for movement of the inner guide stems 19, 20, of said valves. In the present improvement the partitions 21, 21 constitute lateral extensions of the vertical wall of the l central chamber of the main valve casing 1,

and at the ends remote from the outlet neck 31 hereinafter described, said partitions are integrally connected to the wall of the casing 1, while at the ends next adjacent to said outlet neck, said partitions are spaced from the wall of the casing to provide narrow vertical passages through which the passing waters are directed in a curved path toward each other to commingle and attain a uniform mixture before reaching the outlet neck i 22, 22 designate springs arranged in recesses in the closure caps 13, 14, and having bearing against the valve members 17, 18 to yieldinglyl maintain the same in a closed condition, inthe absence of fluid pressure f which in present construction normally tends to 'close said valve members( 23 designates the central operating spindle or stem heretofore referred to as passing through the packing gland 4, and extending into the closed chamber of the main casing 1 aforesaid. At its upper or outer end, the spindle 23 is provided with .an operating handle 24 and an associated pointer 25, for indicating on a curved scale on the upper surface of the main casing 1, the position to which the handle 24 is to be moved to obtain a iow of water of the desired temperature, as usual in the present class of valves.

26 designates a hub secured to the lower end of the operating spindle 23, within the chamber of the main casing 1, and provided with a pair of cam lugs 27 on its periphery. Said cam lugs 27 are irregularly spaced around the circumference of the hub 26, as shown in Fig. 3, so that either cam lug may operate its particular valve member in an independent manner to effect a discharge of either het water or of cold water in accordance with the particular turning adjustment of the hub 26, and so that with a further turning adjustment, effecta mixed discharge of hot and cold Water.

l 28 designates a fixed stop lug in the interior ofthe main casing l, adapted for en# gagement in a sector shaped recess 29 in the hubV 26 aforesaid, and adapted to limit the turning adjustment of said hub in either direction.

30 designates a pair of intermediate arms or levers pivoted at one end in the interior of the main casing 1 andindividual to the respective valve stems 19, 20, and4 disp'sed between a valve stem and its associated cam" lug with said cam lug bearing against one side of the arm or lever and` with the valve stem bearing against the opposite side of the arm o r lever, as illustrated in Fig. 3.

31 designates a tubular neck on the bottom wall 2 of the main casing 1 to constitute the,v

outlet passage thereof, and in the preferred construction shown, said neck is externally screw-threaded for the reception of a union the lowerend of a conical strainer now to coupling 32 by which a suitable outlet nozzle 33, is secured to said tubular neck. The outlet nozzle' is preferably of the horizontally adjustable type shown, and is formed with an enlarged chamber 34 at the intersection of its vertical and horizontal passages.

35 `designates a hollow cap lnut closing an opening in the underside of the aforesaid chamber 34 and adapted to receive and hold be described.

mesme '-36 designates a strainer -of wire gauze or the like, and .preferably of the inverted cone form shown, with its lower and smaller end Aengaging in the cavity of the cap nut 35, to be held in proper position by such engagement of the parts. v

Having thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is

1. Ina mixing valve, .the combination of a main casing having a central circular mixing' chamber, an eccentrically arranged bottom outlet housing and a pair of alined inlet housings se arated from the central chamber by a pair of deflecting partitions which extend from portions of the circular Wall of the mixing chamber to spaced relation to opvide tangential passages next to lsaid wall, and a pair of longitudinally alined valves arranged in said inlet housings, and means for operating said valves, substantially as` set forth. l

2. In a. mixing valve, the combination of a main casing having a central circular mixing chamber, -an eccentrically arranged bottom outlet housing and a pair of alined inlet housings separated from the central ch-amber by a pair of deflecting partitions which4 extendk from portions of the circular wall of the'mixingchamber'to spaced relation to opposed portions of said circular wall to provide tangential lassages next to said wall, and a pair ofp longitudinally alined valves arranged in said inlet housings, and


posed portions of said circular wall'to pro-
